Available on crate feature e2e-encryption only.

The error type for failures while trying to log in a new device using a QR code.

Variants

OAuth(DeviceAuthorizationOAuthError)

An error happened while we were communicating with the OAuth 2.0 authorization server.

LoginFailure

The other device has signaled to us that the login has failed.

Fields

reason: LoginFailureReason

The reason, as signaled by the other device, for the login failure.

homeserver: Option<Url>

The homeserver that we attempted to log in to.

UnexpectedMessage

An unexpected message was received from the other device.

Fields

expected: &'static str

The message we expected.

received: QrAuthMessage

The message we received instead.

SecureChannel(SecureChannelError)

An error happened while exchanging messages with the other device.

CrossProcessRefreshLock(CrossProcessRefreshLockError)

The cross-process refresh lock failed to be initialized.

UserIdDiscovery(HttpError)

An error happened while we were trying to discover our user and device ID, after we have acquired an access token from the OAuth 2.0 authorization server.

SessionTokens(Error)

We failed to set the session tokens after we figured out our device and user IDs.

DeviceKeyUpload(Error)

The device keys failed to be uploaded after we successfully logged in.

SecretImport(SecretImportError)

The secrets bundle we received from the existing device failed to be imported.

ServerReset(Error)

The other party told us to use a different homeserver but we failed to reset the server URL.

impl Error for QRCodeLoginError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str
